I really like where some of this is going Andrea and I'm especially happy someone else has an interest in both 3D and 40k. Myself I'm currently professionally employed as a 3D and motion graphics Artist.
I really like the level of detail you're getting on the actual geometry itself, although I hope you're using some sort of displacement projection for some of the smaller things like the emblazoned logos, working with all those polys could be killer.
Texturing needs some work but I do like that you've given it a 'painted' feel that is a homage to the minis.
If it wasn't horribly shakey legal ground I'd suggest you consider getting your model 3D printed at the end of this
